EMB, ERJ, WHATEVER .... THE REAL PROBLEM IS THAT THESE AIRCRAFT WERE ONLY BUILT IN 7/8 SCALE. THEIR SEATS ARE PRACTICALLY UNUSEABLE BY ANYONE OVER 6'.
IF AC DEFINE 'PROGRESS' AS REPLACING A319 SERVICES WITH TOY AIRPLANES, THEY CAN GIVE IN TO WESTJET NOW.
I PAYS ME MONEY, I TAKES A 737-700 ANY DAY ......
